Great question! It’s a common misperception that web based apps will not be accepted by Apple based on the simple fact that they are web based. There are many WebView based apps available in the App Store, and there are plenty of WebView based templates available across the web, including Web2App.
However, that doesn’t mean that any app published with Web2App (or any other WebView template for that matter) will always be accepted by Apple. If you app is only a simple frame of your site, chances are your app could be rejected.
To get started, it is crucial that your content is mobile ready or responsive, and feels like a native app. For this, we encourage the use of Frameworks like JQuery Mobile, Polymer, IONIC, etc to provide you app with a good mobile optimized user interface. Next, make sure to use plenty of the native functionalities we offer, like the use of tabs, hiding bars, and adding offline support.
Therefore, the purchase of Web2App will not guarantee the approval of your app to the App Store. Only the appropriate use of this template preferably using as much native UI elements as possible, like our tabs will ensure an App Store Approval.
Some examples of sites that look like apps and would be accepted by Apple using Web2App:

Note that for example aliexpress.com and ebay.com offer a similar experience, and that both offer a mobile site, but the aliexpress mobile sites feels like a mobile app, it doesn’t have typical website elements (header, footer, link texts) but it has elements that appear in mobile apps (menu drawer, toolbar, buttons, elevation).
